drm/sun4i: Fix DE2 VI layer format support

2020-03-03T21:44:29+00:00

DE2 VI layer doesn't support blending which means alpha channel is ignored. Replace all formats with alpha with "don't care" (X) channel.

drm/sun4i: Add separate DE3 VI layer formats

2020-03-03T21:44:03+00:00

DE3 VI layers support alpha blending, but DE2 VI layers do not. Additionally, DE3 VI layers support 10-bit RGB and YUV formats. Make a separate list for DE3.

drm/sun4i: de2/de3: Remove unsupported VI layer formats

2020-03-03T21:43:45+00:00

YUV444 and YVU444 are planar formats, but HW format RGB888 is packed. This means that those two mappings were never correct. Remove them.

Revert "drm/sun4i: drv: Allow framebuffer modifiers in mode config"

2020-01-27T09:42:10+00:00

This reverts commit 9db9c0cf5895e4ddde2814360cae7bea9282edd2. Setting mode_config.allow_fb_modifiers manually is completely unnecessary. It is set automatically by drm_universal_plane_init() based on the fact if modifier list is provided or not. Even more, it breaks DE2 and DE3 as they don't support any modifiers beside linear. Modifiers aware applications can be confused by provided empty modifier list - at least linear modifier should be included, but it's not for DE2 and DE3.

drm/sun4i: drc: Make sure we enforce the clock rate

2020-01-08T08:14:08+00:00

The DRC needs to run at 300MHz to be functional. This was done so far using assigned-clocks in the device tree, but that is easy to forget, and doesn't provide any other guarantee than the rate is going to be roughly the one requested at probe time. Therefore it's pretty fragile, so let's just use the exclusive clock API to enforce it.

drm/sun4i: tcon: Set RGB DCLK min. divider based on hardware model

2020-01-07T14:56:40+00:00

In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.") it was assumed that all TCON variants support a minimum divider of 1 if only DCLK was used. However, the oldest generation of hardware only supports minimum divider of 4 if only DCLK is used. If a divider of 1 was used on this old hardware, some scrolling artifact would appear. A divider of 2 seemed OK, but a divider of 3 had artifacts as well. Set the minimum divider when outputing to parallel RGB based on the hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20) hardware, and a minimum of 1 for the rest. A value is not set for the TCON variants lacking channel 0. This fixes the scrolling artifacts seen on my A13 tablet. Fixes: 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.")
